Recommendations for a jazz record which demonstrates vinyl superiority over digital

@atmasphere

Thanks for your detailed advice!  I have a lot of classical CDs and SACDs where the original was mastered on Westrex systems, mainly Mercury Living Presence. I also have vinyl records where the master is stated to be digital on the sleeve, for example Telarc recordings.

I don't mind random pops and ticks, but a few of my records have scratches which might be mitigated on a better deck.  I have a couple of HOMM cartridges so nowhere near state-of-the-art.  I have invested in an Achromat platter mat to control vinyl resonances, plus a puck and carbon fibre brush.

I have an entry-level Krell KSB-7B pre-amplifier with external power supply so I doubt that RFI is a problem there, but who knows?

@lewm and everybody else!  Yes, I have a mountain of advice on what jazz records to buy, and I am sifting through it all.

Meanwhile if I spot new classical record releases with excellent reviews for a fifth or a tenth of the cost of the best audiophile jazz, I'll grab them!

Your Krell preamplifier likely has a very wide bandwidth, which makes it susceptible to RFI in the environment, though perhaps not a source of RFI. RFI can get in by radiation from an outside source like a radio antenna or on the AC line via wires or on an IC connector, also via traveling on the wire.

IC?  NFI! 

RFI = Radio Frequency Interference

I have an entry-level Krell KSB-7B pre-amplifier with external power supply so I doubt that RFI is a problem there, but who knows?

@richardbrand The RFI is injected directly into the phono input by the tonearm cable. If the preamp has provision for 'cartridge loading' then yes, its susceptible.
